JJ Abrams, the award-winning American writer and producer behind hits such as Lost, will be live on MediaGuardian.co.uk this Friday for an exclusive webchat about his new Sky1 drama Fringe.

The Emmy and Golden Globe winning writer and producer, who was also behind the cult movie Cloverfield and TV series Alias, has agreed to answer your questions from his Los Angeles base from 6pm BST (that's 10am LA time, folks).

Fringe, Abrams' latest sci-fi series, launched on Sky1 on Sunday with a literally jaw dropping opening scene in which the passengers on an airliner find their faces disintegrating – you can catch the clip above.

It is certainly dramatic and sets the scene for the rest of the series.

For those coming late to the show, it's name refers to the aspects of 'fringe science' such as telepathy and levitation that are investigated by FBI agent Olivia Dunham, scientist Walter Bishop and his son Peter.

The pilot of the show, rumoured to have cost $10m, is said to have beaten Abram's Lost as the most expensive of all time.

However, it certainly worked - Fox, Fringe's US broadcaster, recently gave the show a big vote of confidence by ordering a full 22 episode first series.

Of course, Abrams is most well known for Lost, which also airs on Sky1 in the UK. Based around the passengers of an airliner which crashes on a mysterious island, it is one of the most expensive TV series ever made.

However, it will end after its sixth series in 2010.

Please post your questions on this blog now and then return on Friday at 6pm BST to see how Abrams answers them.

PS - So as not to give away any plots that haven't been seen yet in the UK, please steer clear of too specific questions about Fringe and season five onwards of Lost.
